The best application forms you know?

Question

User interface

That is, we need to get a significant amount of information from the visitor before we can offer him a certain result (in my case, a service).
As an example: ordering tours/air tickets, gift shops (if you don’t know what to give), content filtering in aggregators, etc.
Stuff like this is often annoying. What would you highlight?
Thank you very much in advance.

Answer 1

Here, I speak as a user who hates filling out forms, the approach is more important than the form itself. For example, first ask for a name and email. Ok, no problem.
Then display the goods (I give an example with a gift shop) and write:
Thank you for registering! Unfortunately, based on your name alone, we can only offer popular items among our customers. Share with us other data and we can find something else.
I know it sounds a little idiotic and the sentences should be shortened, but the bottom line is that you need to approach the issue from an emotional point of view.
So far, I've only read on this topic by Aaron Walter, Emotional Web Design. I liked the book, but it was short. An example is given with dropbox, which, in order to be promoted in social networks (which also infuriates to a certain extent), created a kind of game, connect friends and colleagues - get more space. Personally, I collected all possible places :) In general - an emotional approach is the first option.
Second - look at social networks, for example VKontakte. How do they force you to fill out a profile? I think the answer is interest. But whether you can interest someone in the gift shop to sit an extra 10-20 minutes filling out a profile ... it's hard to say.

Answer 2

Thanks for the answer. It seems to me that it is better to do it in the form of a wizard, for each screen a couple of questions. And how to understand how to arrange these questions so that the person does not leave?

Answer 3

I would recommend sticking to the principle of step by step in the form. Each step of which reflects the degree of user involvement in the process (no more than 3 steps). Starting with minimal interest in the first step, it will be enough to find out the name and main contact and then expand on the topic. It is important to remember about the logic of building a purchase in specific business processes that are relevant for this particular site.
